Electrochromic Fiber Membrane by Electrospinning Method

In this paper, poly(vinylpyrrolidone) is used as the matrix to prepare poly(3,4-ethylenedioxythiophene)/ polyvinylpyrrolidone (PEDOT/PVP) conductive fiber membranes by combining electrospinning and gas phase polymerization. The process conditions were controlled to obtain fibers with good morphology. The fiber was characterized by SEM, FTIR, four-electrode method, electrochemical workstation and other analytical methods. The results show that the fiber conductivity can reach 6.9×10-3S/cm, and it has good reversible electrochromic properties and can change color between bule and light blue grey.
